How to use the Periodic Table to identify alkali metals, alkaline earth metals and transition metals, and trends in ionization energy, electronegativity, and the relative sizes of ions and atoms.

Students Will be able to:

Recognize & identify the groups & periods on the periodic table and be able to predict the trends in ionization energy, electronegativity and sizes of ions and atoms based on their position in the periodic table.

Know that when an observation does not agree with an accepted scientific theory, sometimes the observation is mistaken or fraudulent (e.g., Piltdown Man fossil or unidentified flying objects), and sometimes the theory is wrong (Ptolmaic model of movement of the sun, moon, and planets).
